In the drawings, Figure l is a section through the neck of an upright bottle and.

my stopper connected therewith, Fig. 2a corresponding end view, Fig. 3 a side view of the stopper shell, Fig. 4: an outer and Fig. 5 an inner end view. Figs. 6 and 7 are functional sections, Fig. 6 illustrating the act of pouring and Fig. 7 the automatic losure of the stopper when the bottle is held at any angle between vertical andhorizontal. Fig. 8 is a sectional view of a preferred form.

To prepare a bottle 1 for my stopper, the neck is formed with an exterior attachment shoulder, 2, and terminates in a nozzle, 3, whose inner walls contract to form a valve seat 4, which may be of any contour, and is illustrated as an annular plane. I provide a valve shell 5, preferably made of porcelain, and comprising. a cylindo-conoidal axial body 6 containing an outwardlyclosed tubular valve chamber 7 ,whose inner surface merges into the conical inner surface, .8, of a conoidal closure, 9, and on whose cylindrical exterior staggered baffles 10 are formed, which fit the nozzle 3 and Whose staggered openings 11, form a sinuous discharge passage 12; and a mouthpiece 13 adapted for a cork and united with the axial body 6 by arms 14 and provided with an outer shoulder 15 for engagement with a suitable tubular spun-metal clamp 16, which clamps the shell 5 firmly to the bottle and makes a tight joint between them.

In the valve chamber 7, I locate avalve 17,il1ustrated as a short tube, and exterior thereto a weight,preferably a glass ball 18.

In order that the valve may not be fiuid bound it is necessary to provide a way communicating the outer part of the valve A oMurmur-PREVE TING DEVICE.

" 'c hamber, ,withthoatmosphere or with the; bottle, which might be done by chanlneling theexterior of the valve or perforatthe.wall of. the charnber. Both these methodsare objectionable. If the wall were perforated, a. tube ,could be applied to the hole andthe valve thereby sucked oitits ,seatfl. .lVhile; thereisnotroom to channel the valve without too greatly reducing the width ,of the valve seat. f Moreover, exper ence proves, that gthe tubular valve moves more freely and seats with less effortmthan FWYQ ERQ because ,thegtotal: volume coa tained within the bottle, valve chamber and ya ve bore is;constant and the valve can the component which becomes greater as the dip of the bottle becomes less, becomes maximum when it is upright and which presses the valve 17 to its seat 4. When thebottle is tilted in the act of pouring, and the conical surface 8 upon which the ball rests, declines beyond the horizontal, the ball no longer exerts its pressure on the valve, and the valve falls forward by gravity. The fluid then passes through the lower part of the sinuous discharge passage, while the air enters through the upper level of said passage, as illustrated in Fig. 6. "When the bottle is brought back nearly to or to horizontal, the ball rolls back upon the surface 8 against the valve 17, presses it to its seat, and seals the bottle against the entry of liquid. In Fig. 8 is disclosed a modified form of the foregoing described stopper, the change in structure, however, not affecting the prin ciples described, the said changes being I portion 13, when in position, retains the conoidal member 6 in. operative position through adhesion to the said portion 13, the two said members being placed together and baked while in this position, thereby practically forming an integral member. The only advantage in the above noted con struction over that disclosed in Fig. 1 is in the purpose o1 chcapening the molds and to insure economy in the manufacture of the article.

1 claim as new and desire to protect by Letters Patent:

1. In combination with a bottle neck and a valve seat therein, a fixed, axial, cupshaped body containing an outwardly closed conical chamber, expanding inwardly into a cylindrical chamber, a tubular valve adapted to coact with said seat, a spherical Weight adapted when the bottle is substantially horizontal to rest upon the conical Wall of said chamber and against the valve, to close it, and sinuous passages circumferential and form therewith sinuous passages with staggered baffies, a valve adapted to coact with said seat, a spherical weight adapted when the bottle is substantially horizontal to rest upon the conical. wall of said chamber and against the valve, to close it.
